Week 8 Positioning of Toes

These flashcards cover key concepts of radiographic positioning and procedures for imaging the toes, ensuring thorough preparation for the upcoming exam.

What is the CR angle for an AP view of the toes when joint spaces are a concern?

15 degrees cephalad.

What is the centering point (CP) for an AP view of the toes?

MTP joint of the affected toe.

What should be included in the structures for an AP toe radiograph?

Distal metatarsals and all phalanges.

In what position should the patient be when taking an AP view of the toes?

Sitting or lying on the table.

What should the knees do during an AP toe x-ray procedure?

Flex and can rest together for support.

How should the affected toe be aligned with the IR in an AP view?

Long axis of the toe aligned with long axis of IR.

What should be done to open joint spaces in the AP view of the toes?

Add a sponge or angle the tube 15 degrees cephalad.

In an AP Oblique view, how much should the leg and foot be rotated?

30-45 degrees medially.

What is the main goal of rotation in an AP Oblique toe x-ray?

To make the plantar surface more concave and the dorsal surface almost straight.

What pattern should ST width be in an AP Oblique image?

2:1 for plantar to dorsal.

What is the centering point for the lateral view of toes 2-5?

PIPJ of the affected toe.

What is the centering point for the lateral view of the great toe?

IPJ of the affected toe.

What is the position of the patient for a lateral view of the great toe?

Turned on the unaffected side.

What is the position of the patient for a lateral view of toes 3-5?

Turned on the affected side.

What surface of the toe should be perpendicular to the IR in a lateral view?

Plantar surface of the toe.

What is the key alignment for a lateral view of the toe?

Long axis of toe to long axis of IR.

What should be evident in a properly taken lateral toe x-ray?

Open IPs and MTP joints.

In lateral positioning, what should the condyles show?

SI in the anterior/posterior direction.

What should be done in terms of digit separation during toe radiography?

Separate the toes, if possible.

What should you avoid doing if an obvious deformity is present on the toe?

Do not manipulate the toe.

What is the minimum distance of distal metatarsals to be included in toe imaging?

1 inch proximal to the affected MTP joint.

How should the long axis of the toe relate to the long axis of the IR in any toe view?

Aligned with each other.

What positioning aids can be used for the heel during an AP view?

Support heel with a pad if needed.

What is the significance of having adequate rotation in an AP Oblique view?

To ensure proper concavity of the plantar surface.

What is the impact of poor alignment in radiographic imaging of the toe?

Poor visualization of joint spaces and toe structure.

What is the ideal condition for the ankle and foot during toe positioning?

Foot flat on the IR.

Which metatarsal is generally the most proximal during imaging?

5th MTP joint.

What must be considered when aligning the toes for radiographs?

No rotation.

What is a crucial step to take when preparing for toe imaging involving multiple toes?

Center and align the affected toe appropriately.
